Here is a thought, maybe GRUB is installed to your MBR, but maybe it's
installed to the wrong MBR.  This can happen if your system.map file
(I think that's the name) has mapped your drives incorrectly.  This
becomes more likely if you have PATA and SATA drives.
If you want to test this, try swapping the drives momentarily to see
if you get a "No operating system found" error or if GRUB comes up. 
Even if GRUB comes up, though, it is probably the case that your
system won't boot; it will get confused with the drives in the wrong
order.
Now to actually fixing the problem : ).  Boot with the rescue CD (CD
1/DVD with "linux rescue") and when it is finished run:

chroot /mnt/sysimage/
grub-install /dev/hda
exit
exit

You also might need to run grub-install with the --recheck option to
rebuild the map file if it is wrong.

You can have the best of both worlds.  Install the 64-bit version,
install one 64-bit browser and another 32-bit browser.  Then use the
32-bit browser for when you need java and flash.  Otherwise, use the
64-bit one.  Why so picky? ; )
